The optimizer is called by some of the individual optimizers to avoid
this problem. If some neglect to do so, they can be fixed.
It can't be done bottom-up without being a separate
pass. I don't think that's worth it.
Having all appropriate optimizers which test subforms first call
OPTIMIZE on those subforms should work fine. That makes the
organization effectively bottom-up, though there may be some
redundant tests which determine that an already-optimized form
need not be optimized again. I agree that a separate pass probably
is not worth it.
